Abstract
Description
Die Erfindung bezieht sich auf eine elektrische Zahnbürste, wobei sich ein Bürstenteil in einem begrenzten Bogen hin und her dreht, wobei die elektrische Zahnbürste ein Antriebselement, welches sich in einem ausgewählten Bewegungsumfang bewegt, sowie eine Rotationsfeder umfasst.The invention relates to an electric toothbrush, wherein a brush part rotates in a limited arc back and forth, wherein the electric toothbrush comprises a drive element which moves in a selected range of motion, and a rotation spring.
Unter einer Rotationsfeder ist eine Feder zu verstehen, die sich bei Krafteinwirkung in einer Richtung verdreht, dabei Energie speichert und dann beim Nachlassen der Kraft zu oder in Richtung ihrer Ursprungsposition zurückkehrt. Derartige Rotationsfedern sind allgemein wohlbekannt und zahlreiche Anordnungen führen diese einfache rotierende Bewegung aus.By a rotational spring is meant a spring which twists in one direction upon application of force, storing energy and then returning to or returning to its original position upon release of the force. Such rotary springs are generally well known and many arrangements perform this simple rotary motion.
Bei bestimmten Anwendungen ist es zwar nicht notwendig, typischerweise aber wünschenswert, dass eine Rotationsfeder eine symmetrische Federkonstante (sowohl im Uhrzeigersinn als auch entgegen dem Uhrzeigersinn) aufweist und zugleich kostengünstig und einfach herzustellen ist. Die vorliegende Erfindung bezieht sich auf eine elektrische Zahnbürste mit einer kostengünstigen Rotationsfeder mit symmetrischer Federkonstante. Dies wird mit einer elektrischen Zahnbürste nach Anspruch 1 erreicht.While not required, it is typically desirable in some applications for a rotary spring to have a symmetrical spring constant (both clockwise and counterclockwise) while being inexpensive and easy to manufacture. The present invention relates to an electric toothbrush with a low-cost rotational spring with symmetrical spring constant. This is achieved with an electric toothbrush according to claim 1.

Die Schenkelbauteile
Das Trägerbauteil, das obere Bauteil und die Schenkelbauteile können aus verschiedenen Materialien hergestellt sein. Zum Beispiel können sie aus Metall oder Kunststoff, beispielsweise durch Spritzguss aus elastomerem Material, hergestellt sein. Jedes Material muss jedoch die Fähigkeit besitzen, wiederholt zu oder in Richtung seiner Ursprungsposition zurückzukehren, nachdem es in einer Richtung verdreht oder gedreht wurde. Es muss über lange Zeit eine gleichbleibende Funktion bereitstellen.The support member, the upper member and the leg members may be made of different materials. For example, they may be made of metal or plastic, for example by injection molding of elastomeric material. However, each material must have the ability to repeatedly return to or return to its original position after being twisted or rotated in one direction. It must provide a consistent function for a long time.

Bei der Zahnbürste ist die Rotationsfeder
Während des Betriebs der Federanordnung von
Die Rotationsfeder der vorliegenden Erfindung umgibt das Antriebsbauteil für die Feder. Bei einer Ausführungsform besteht die Feder aus einem einheitlichen Stück. Sie könnte auch aus mehreren Segmenten bestehen. Die Federkonstante kann durch Auswahl der Materialien für die Feder und der Abmessungen der Feder sowie der Anzahl der Schenkel variiert werden. Die Schenkelbauteile können mit einer Schicht aus einem elastomeren oder einem anderen Material umgossen werden, um für die Feder eine Einhausung zu schaffen, die einen vollständigen Kopfabschnitt für das Gerät bildet.The rotary spring of the present invention surrounds the drive member for the spring. In one embodiment, the spring is a unitary piece. It could also consist of several segments. The spring constant can be varied by selecting the materials for the spring and the dimensions of the spring as well as the number of legs. The leg members may be encapsulated with a layer of elastomeric or other material to provide the spring with an enclosure that forms a complete head portion for the device.
Die Rotationsfeder der vorliegenden Erfindung, welche das Antriebsbauteil umgibt, macht Mehrfachfedern oder Federn, die sich bei einer typischen Rotationsfederanordnung um eine Antriebswelle bewegen müssen, überflüssig. Die vorliegende Feder bewirkt eine symmetrische Federkonstante und eine gleichmäßige, zuverlässige Funktion und lässt sich relativ kostengünstig und leicht herstellen.The rotary spring of the present invention, which surrounds the drive member, eliminates the need for multiple springs or springs which must move about a drive shaft in a typical rotary spring arrangement. The present spring provides a symmetrical spring constant and smooth, reliable function, and is relatively inexpensive and easy to manufacture.
